Location of the Black Sea
- Black Sea - inland sea of the basin Atlantic Ocean.
- The Bosphorus connects with the Sea of Marmara, then, through the Dardanelles, with the Aegean and mediterranean seas. The Kerch Strait connects with the Sea of Azov.
- From the north, the Crimean peninsula cuts deep into the sea.
- The water boundary between Europe and Asia Minor runs along the surface of the Black Sea.
- The sea is - inland

Area, depth and length of the Black Sea coastline
- The area of the Black Sea is 422,000 km² (according to other sources - 436,400 km²). The outlines of the Black Sea resemble an oval with the largest axis about 1150 km. The greatest length of the sea from north to south is 580 km. The greatest depth is 2210 m, the average is 1240 m. The volume of water in the sea is 555 thousand km3
- Square Sea of Azov 38 thousand km 2, maximum depth- 14 m, average - 8 m.

Salinity of the Black Sea
- The salinity of the Black Sea is not high compared to other seas and oceans. In the surface layer, there are only 18 grams of salts per 1 thousand grams of water. For comparison, in the Atlantic Ocean it is 35 grams of salt, and in the Red Sea - 39 grams of salt.
- In the north-west of the Black Sea, the salinity is even lower, only 13 grams of salt per 1 thousand grams of sea water.

Depths
- Maximum depth: 2210 m
- Average depth: 1240 m
- In the depths of the Black Sea, below 200 meters, there is no oxygen at all, and only anaerobic saprotrophic bacteria live there, continuing the decomposition of the remains of the living, sinking from the upper layer of the sea.

Flora and fauna of the Black Sea
In total, there are more than 660 species of plants and 2000 species of representatives of the animal world in the Black Sea. The resources of the Black Sea, namely anchovy, horse mackerel, sprat, mullet, flounder, mackerel, etc., algae and invertebrates (mussels, shrimps, oysters) are of industrial importance. The sea produces up to 300 thousand tons annually biological resources. Industrial reserves of combustible gas and oil have been explored here.

The Black Sea is an inland sea of the Atlantic Ocean basin. The Bosporus connects with the Sea of Marmara, then, through the Dardanelles - with the Aegean and Mediterranean Seas. The Kerch Strait connects with the Sea of Azov. The water boundary between Europe and Asia Minor runs along the surface of the Black Sea. There are few islands in the Black Sea. The largest island is Dzharylgach, its area is 62 km². highest point- 2 m. The rest of the islands are much smaller, the largest ones are Berezan and Serpentine (both with an area of \u200b\u200bless than 1 km²).The shores of the Black Sea are scarcely indented and,
mostly in the northern part.
The only large peninsula is the Crimean.
The following flows into the Black Sea major rivers: Danube, Dnieper, Dniester, as well as smaller Mzymta, Psou, swell, Rioni, Kodori(Kodor), Enguri(in the east of the sea), Chorokh, Kyzyl-Irmak, Ashley-Irmak, Sakarya(on South), Southern Bug (in the north).
In the Black Sea, due to its desalination by rivers, there are two masses, two layers of water, which weakly mix with each other.
mountain river
The main Black Sea Current is directed counterclockwise along the entire perimeter of the sea, forming two noticeable rings (“Knipovich glasses”,
named after one of the hydrologists who described these currents).
The climate of the Black Sea, due to its mid-continental position, is mainly continental.
Black Sea coast of the Caucasus and the southern coast of Crimea are protected by mountains from cold northern winds and, as a result, have a mild mediterranean subtropical climate.
The waters of the Black Sea are not subject to freezing.
The water temperature does not drop below +8 °C
The Black Sea is an important transportation area, as well as
one of the largest resorts
regions of Eurasia.
The largest port cities on the Black Sea:
Novorossiysk, Sochi, Tuapse (Russia)
Burgas, Varna (Bulgaria)
Batum, Poti (Georgia)
Sukhum (Abkhazia / Georgia)
Constanta (Romania)
Samsun, Trabzon (Türkiye)
Odessa, Evpatoria, Ilyichevsk, Yuzhny, Kerch, Sevastopol, Yalta (Ukraine)
A characteristic feature of the Black Sea is the complete absence of life.
at depths over 150-200 m due to the saturation of deep water layers with hydrogen sulfide
The flora of the sea includes 270 species of multicellular green,
brown, red bottom algae
Directly from the water's edge, dense thickets of brown algae cystoseira begin.
Cladostephus and corallina
Seaweed Ulva
Enteromorpha
Brown algae scytosiphon
Red algae callitamnion corymbose
Red seaweed Laurencia
Ceramium ciliated
2.5 thousand species of animals live in the Black Sea
(of which 500 species unicellular, 160 kinds vertebrates- fish and mammals, 500 species crustaceans, 200 kinds shellfish, the rest - invertebrates different types).
Among the main reasons for the relative poverty of the animal world of the sea:
- wide range of water salinity
- moderately cold water
- the presence of hydrogen sulfide at great depths.

History of the Black Sea
shows that the person
much more dangerous for the sea and its
inhabitants than they are for him.
Children often ask - do crabs bite? They do not bite, but pinch - not with teeth, which they do not have, but with pincers. And only when we ourselves try to grab them. Large marble crab or stone crab can pinch your finger very painfully; if he nevertheless grabbed you, do not pull him - you will tear off the claw. Crabs release their legs and claws, just like lizards release their tail. Better to just leave him alone, he will unhook himself.
Annually October 31 all countries of the Black Sea region celebrate the International Day of the Black Sea.

Black Sea
and its inhabitants
The Black Sea is located in the depths of the Eurasia continent and is inland sea basin of the Atlantic Ocean. The average depth of the Black Sea is 1300 m, and the maximum depth reaches 2211 m. The area is 422 thousand sq. km. The waters of the Black Sea wash the shores of many states: Russia, Ukraine, Bulgaria, Turkey, Romania and Georgia. The salinity of the water in the Black Sea is much lower than in other seas.
Not a single sea on Earth has a depth division into two zones - oxygen (up to a depth of 150-200 m) and lifeless hydrogen sulfide (below 200 m), occupying 87% of its water mass. At the disposal of animals and plants is only 13% of the volume of water.
- Stone crab prefers rocky bottom
- Grass crab lives in algae
About 180 species of fish are known that live in the Black Sea.
The goby hides in a mink
- Scorpion thorns are poisonous
Dogs often settle in rapana shells
Rock groupers are very curious
Stargazer or sea cow very poisonous
Night coloring of red mullet (sultanka)
The sea dragon is very poisonous
The needlefish and seahorse differ from other fish in that their females spawn not into the water, but into special skin folds on the males' backs, and the males hatch their eggs until the fry are hatched ..
Fry horse mackerel find shelter under the dome of the cornerot
High mountains protect a narrow strip of the Black Sea coast of the Caucasus from cold winds from the north. The sun rises high above the horizon here. Even in winter, its rays heat the surface of the earth so strongly that the air temperature remains above zero. At a time when frosts are raging in the north, blizzards are raging, roses are blooming in the local gardens.
Big influence the weather of the Black Sea coast is influenced by the sea How good you are, O night sea, - Here it is radiant, there it is bluish-dark ... In the moonlight, as if alive, It walks, and breathes, and it shines. On the endless, in the free expanse Glitter and movement, roar and thunder ... The sea bathed in a dull radiance, How good you are in the desert of the night! (Tyutchev F. I.)
Indeed, in winter it warms, and in summer it moderates the heat. A lot of water evaporates from the surface of the sea. Water vapor rises and is carried by the winds to the slopes of the mountains. Here it cools and turns into powerful clouds, from which heavy precipitation falls. Heat and moisture create favorable conditions for the development of lush vegetation. Evergreens grow here.
What does the word "subtropics" mean? Translated from Latin, the prefix "sub" means "under". The subtropics are the area under the tropics. More precisely, near tropical zone. subtropical zone located south of Russia, and here on Black Sea coast, is just a small piece. So we need to find out what are distinctive features flora subtropics.
Favorable conditions - heat and moisture - make it possible to grow tall trees with large leaves (beech, oak, chestnut) Beech reaches a height of meters. its trunk is even, the leaves are in the shape of an oblong ellipse, the fruits are nuts, but they cannot be eaten. Beech lives up to 500 years.
Dolphins are toothed whales, only much smaller. These are the most intelligent marine animals, they are wonderful swimmers. Dolphins never leave a relative in white: they support the wounded and sick on the surface so that he can breathe, and help him swim. Dolphins navigate and communicate with each other using sound signals.
Created Sochi national park to save unique nature. The plants of these places are listed in the Red Book of Russia (Colchis needle, Colchis boxwood, yew berry)
